Abstract
A moving toy, e.g. toy car, comprises a body, wheels for moving the body on a surface, and an electric motor provided in the body for driving the wheels. A control circuit is connected to the motor for controlling the performance of the motor. Also included one or more impact detectors connected to the control circuit for detecting an impact acted upon the toy and in response providing a signal to cause the control circuit to reduce the performance of the motor and hence the speed of the car.
Claims6
A moving toy comprising:
- a body;
- rotary means for moving the body on a surface;
- an electric motor provided in the body for driving the rotary means;
- a control circuit connected to the motor for controlling the performance of the motor;
- and
- at least one impact detector connected to the control circuit for detecting an impact acted upon the toy and in response providing a signal to cause the control circuit to reduce the performance of the motor,
- including a plurality of said impact detectors provided at different positions of the toy, each for detecting an impact acted upon the toy in the region of the corresponding position, for providing corresponding signals causing the control circuit to progressively reduce the performance of the motor.
